TECHNICAL FIELD

The present disclosure relates to a method and device for providing information regarding an object. More particularly, the present disclosure relates to a method and device for providing information regarding an object by sensing a user's gesture regarding the object, and according to the user's gesture that is sensed, providing information regarding the object via a pre-determined device.

BACKGROUND

With miniaturization of computers and the development of a network among devices, a ubiquitous computing environment has been established in recent times. In a near future, periphery objects within a home or an office will have a computer installed in them, contributing to enriching human life. A change like this may cause a need for direct interactions with general objects (particularly, such as papers or books), which previously were incapable of being linked to a digital system.

Currently, when a user tries to store information written on papers in a mobile device, it is required for the user to record the information written on the papers by driving a camera of the mobile device, and for the mobile device to store it by post-processing the recorded image. Or, the user needs to have a Personal Computer (PC) recognize the information written on the papers, for example by means of a scanner, and the PC needs to transmit the recognized information to the mobile device by post-processing it. Therefore, a system for providing direct and simple interactions between the general objects (particularly papers and books) and digital devices is required.

The above information is presented as background information only to assist with an understanding of the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the present disclosure.

Examples of the short-range wireless communication may include Wireless Fidelity (Wi-Fi), Near Field Communication (NFC), BLUETOOTH®, ZIGBEE®, Wi-Fi Direct (WFD), and Ultra Wideband (UWB), but it is not limited thereto.

The first device 100 may recognize the object 300 and distinguish the object 300 from other objects. Also, the first device 100 may sense a user's gesture regarding the object 300. Descriptions of these aspects will now be made in reference to FIG. 1B.

Referring to FIG. 1B, the first device 100 may sense the user's gesture regarding the object 300 via an image input device 111. The image input device 111 may be a 2-Dimensional (2D) camera or a 3-Dimensional (3D) camera. Also, examples of the image input device 111 may include a depth camera and a multi-view camera. The user's gesture according to an embodiment of the present disclosure may include a tapping, a touching and holding, a double tapping, a dragging, a flicking, a dragging and dropping, and a pinching.

“A tapping” is a movement whereby a user touches an object by using a finger or a touching instrument (for example, an electronic pen), and, without moving, immediately lifts the finger or the touching instrument from the object. “A double tapping” is a movement whereby a user touches the object twice by using a finger or a stylus.

“A touching and holding” is a movement whereby a user touches the object by using a finger or a touching instrument (for example, an electronic pen), and maintains the touching input for more than a particular time (for example, 2 seconds). In other words, “a touching and holding” refers to a case when a time difference between a point of touching-in and a point of touching-out is more than the particular time (for example, 2 seconds). To have the user recognize whether the touching input is a tapping or a touching and holding, if the touching input is maintained for more than the particular time, a visual or auditory signal may be provided. The particular time may vary according to various embodiments of the present disclosure.

“A dragging” is a movement whereby a user touches the object by a finger or a touching instrument, and maintaining the touching movement, moves the finger or the touching instrument to other directions within the object.

“A flicking” is a movement whereby a user drags the object by using a finger or a touching instrument at a rate that is the same or higher than a particular speed (for example, 100 pixel/s). “A dragging and dropping” is a movement whereby a user drags the object to a certain place by using a finger or a touching instrument, and leaves the object there.

“A pinching” is a movement whereby a user touches on a screen with two fingers, whereby the two fingers move in different directions.

The second device 200 may receive content regarding the object 300 from the first device 100 that is connected with the second device 200 in a network. Also, the second device 200 may output the content that is received from the first device 100 on a screen. That is, the second device 200 according to an embodiment of the present disclosure may include a communication unit, an output unit (for example, a display unit, a sound output unit, and a vibration motor), a control unit, a memory, and a user input unit.

The second device 200 may be formed in various forms. For example, the second device 200 may include a cellular phone, a smart phone, a laptop computer, a tablet Personal Computer (PC), an electronic book terminal, a digital broadcasting terminal, a Personal Digital Assistant (PDA), a Portable Multimedia Player (PMP), a navigation device, an MP3 player, and a digital camera, but it is not limited thereto.

Hereinafter, a method in which the first device 100 and the second device 200 provide users information regarding the object 300, according to the user's gesture, will be described in detail, in reference to FIG. 2.

FIG. 2 is a flowchart illustrating a method of providing information regarding an object according to an embodiment of the present disclosure.

Referring to FIG. 2, in operation S210, the first device 100 may sense a user's pre-determined gesture regarding the object 300 located in a certain area. The certain area is an area within which the first device 100 may sense the object 300 or the user's gesture regarding the object 300. For example, the certain area may be an area in which the image input device 111 of the first device 100 may obtain an image regarding the object 300 (i.e. an area that the image input device 111 may record).

The first device 100 may sense the user's pre-determined gesture by using the image input device 111 (for example, a depth camera). The pre-determined gesture may include a gesture selecting all or a part of an area of the object 300, a gesture requesting a capturing of the selected area, a gesture requesting a search of the selected area, a gesture requesting a translation of the selected area, and a gesture requesting a connection of a phone call, for example.

Meanwhile, the first device 100 according to another embodiment of the present disclosure may sense the user's pre-determined gesture by an electronic pen. For example, if the user selects a certain area by drawing a line on a paper on which a specific pattern is printed, via the electronic pen, the electronic pen may transmit coordinates information regarding the certain area that the user selected, to the first device 100. In this case, the first device 100 may identify the area that is selected by the user, based on the coordinate information that is received from the electronic pen.

According to yet another embodiment of the present disclosure, the first device 100 may recognize a user's sound gesture regarding the object 300 via a sound input device (for example, a microphone).

In operation S220, the first device 100 may obtain content regarding the object 300 according to the user's pre-determined gesture. According to an embodiment of the present disclosure, the content may include at least one of an image and a text.

The first device 100 according to an embodiment of the present disclosure may directly generate the content regarding the object 300, or extract the content from the outside or a memory. For example, the first device 100 may capture first content in all or a part of an area the object 300, which is selected according to the user's pre-determined gesture, and generate video content regarding the object 300. Also, the first device 100 may extract (or search) second content (for example, the original content) corresponding to the first content, from a web server or the memory, by using the first content that is captured as metadata.

In operation 5230, the first device 100 may transmit the content regarding the object 300 to the second device 200 that is connected with the first device 100 in a network. The first device 100 may transmit the content regarding the object 300 to the second device 200 via the short-range wireless communication (for example, Wi-Fi, BLUETOOTH®, and so forth). Here, the content regarding the object 300 may be output in the second device 200. The second device 200 may output the content regarding the object 300, by using at least one of a video signal, an audio signal, and a vibration signal.

Therefore, the first device 100 according to an embodiment of the present disclosure may sense the user's gesture regarding an object 300 and provide the content corresponding to the user's gesture for the second device 200, thereby providing users with an experience as if the object 300 that is an analogue device is connected to the second device 200 that is a digital device.

Hereinafter, a method in which the first device provides information regarding the object 300 by sensing the user's gesture will be described more in detail, in reference to FIG. 3.

FIG. 3 is a flow diagram illustrating a method of providing information regarding an object based on a user's gesture according to an embodiment of the present disclosure.

Referring to FIG. 3, in operation S310, the first device 100 and the second device 200 may be connected in a network. The first device 100 may request the second device 200 for a connection, or the first device 100 may receive the connection request from the second device 200.

For example, according to an embodiment of the present disclosure, the first device 100 may recognize a marker of the second device 200 located in a pre-determined position. The marker of the second device 200 includes identification information of the second device 200. The marker of the second device 200 may include barcodes (a one-dimensional barcode, a two-dimensional barcode, and a three-dimensional barcode), a color code, and a BLUETOOTH® Low Energy (BLE) tag. The BLE tag may broadcast the identification information to the outside by a BLE communication.

The first device 100 may identify the second device 200, based on the marker of the second device 200 and then extract connection information of the second device 200 corresponding to the identification information of the second device 200. Also, the first device 100 may request a connection to the second device 200 according to the connection information of the second device 200.

The connection information of the second device 200 may include a communication method of the second device 200, connection information (e.g., Service Set Identifier (SSID), an Internet Protocol (IP) address, a Media Access Control (MAC) address, a channel number, a security key, and so forth) of a wireless Local Area Network (LAN) that is used by the second device 200, a MAC address of the second device 200, a Bluetooth address of the second device 200, a product name of the second device 200, and a profile of the second device 200. The communication method may include a wireless LAN (an ad-hoc mode or an infrastructure mode), BLUETOOTH®, ZIGBEE®, a WFD, and an UWB.

According to another embodiment of the present disclosure, if the user places the second device 200 in a predetermined position, the second device 200 may receive information for connecting with the first device from the NFC tag located in a certain area. Here, the second device 200 may request the first device 100 for a communication connection. The first device 100, based on the connection request received from the second device 200, may connect the communication with the second device 200. The aspect as such will be described in detail below with reference to FIGS. 4A and 4B.

In operation S320, the first device 100 may identify the object 300 located in a certain area.

The first device 100 may capture an image of the object 300 via the image input device 111. The first device 100 may identify the object 300, based on the captured image of the object 300. In other words, the first device 100 may search for information regarding the object 300 from the memory or the external server by using the captured image of the object 300 as metadata. For example, when the object 300 is a book, the first device 100 may capture a title, a cover, a character image of the book, and search for the object 300 from the memory or the external server by using the captured image. Here, the first device 100 may identify the object 300 based on the search result, and obtain detailed information (for example, a title of the book, a published year, a publisher, and an author) regarding the object 300.

According to another embodiment of the present disclosure, the first device 100 may identify the object 300 by using a marker included in the object 300. The marker included in the object 300 may include identification information of the object 300. The marker included in the object 300 may include a one-dimensional barcode, a two-dimensional barcode (for example, a quick response code), a three-dimensional barcode, a grey code, a color code, and a BLE tag.

When the marker included in the object 300 is a barcode or a color code, the first device 100 may recognize the marker by using the image input device 111. Also, when the marker included in the object 300 is a BLE tag, the first device 100 may receive the identification information of the object 300, which is broadcasted by the BLE tag.

In operation S330, the first device 100 may sense the user's pre-determined gesture that is selecting all or a part of an area of the object 300. According to an embodiment of the present disclosure, the first device 100 may sense the user's pre-determined gesture by using the image input device 111. According to another embodiment of the present disclosure, the first device 100 may sense the user's pre-determined gesture by using the electronic pen. Meanwhile, according to an embodiment of the present disclosure, the first device 100 may display an identification of all or the part of the area that the user selected, by using, for example, a projector.

In operation S340, the first device 100 may capture first content in all or the part of the area of the object 300. Further explanation regarding operations S330 to S340 are provided with reference operations S210 to S220 of FIG. 2, and thus will be omitted.

In operation 5350, the first device 100 may transmit the first content, or second content that corresponds to the first content.

That is, the first device 100 may transmit the first content itself, which captured all or the part of the area of the object 300, which is selected by the user to the second device 200. Or, the first device 100 may extract the second content from the first content, and transmit the second content to the second device 200.

In operation 5360, the second device 200 may display the first content or the second content. Thus, the user may receive a response of the predetermined gesture regarding the object 300 via the second device 200.

FIGS. 4A and 4B are views illustrating a method in which a first device recognizes a second device according to an embodiment of the present disclosure.

According to an embodiment of the present disclosure, there may be a plurality of devices in proximity to the object 300, thus, the first device 100 may have to specify the second device 200 of the plurality of devices, which could be connected with the object 300.

As illustrated in FIG. 4A, if the user places the second device 200 in a predetermined position 400, the second device 200 may receive data from the NFC tag existing in the predetermined position 400. For example, the second device 200 may receive identification information (for example, an ID) of the NFC tag, or connection information (for example, identification information of the second device 200, information of a wireless LAN that is used by the second device 200, and a BLUETOOTH® address of the second device 200) for connecting with the second device 200 from the NFC tag. The second device 200, based on the received data, may request a connection to the first device 100. Here, the first device 100 may specify the second device 200, which requested the connection, as a device connected with the object 300.

As illustrated in FIG. 4B, the first device 100 may sense the user's pre-determined gesture regarding the second device 200 and specify the second device 200 out of at least one device. The first device 100 may sense the user's pre-determined gesture via the image input device 111. For example, the first device 100 may specify a device that is touched by the user for more than the predetermined time (for example, 10 seconds or more) as the second device 200.

FIGS. 5A and 5B are views illustrating a screen on which a second device displays content corresponding to a certain predetermined area of an object, which is selected by a user according to an embodiment of the present disclosure.

Referring to FIG. 5A, the first device 100 may sense the user's gesture selecting a part of an area of the object 300. For example, the first device 100 may sense the user's gesture selecting a part of an area 500 of the object 300 by drawing a line by fingers or a pen.

Referring to FIG. 5B, the first device 100 may capture an image in the part of an area 500 selected by the user. In addition, the first device 100 may transmit the captured image itself to the second device 200 so that the second device 200 may display the captured image.

Also, the first device 100 may obtain the original image corresponding to the captured image and transmit the original image to the second device 200. For example, if the object 300 is a book, the first device 100 may obtain data regarding the original book from the memory or the external server, and extract the original image corresponding to the image captured from the original book. Also, the first device 100 may transmit the original image to the second device 200 so that the second device 200 may display the original image.

That is, the first device 100 according to an embodiment of the present disclosure may selectively transmit the captured image and the original image to the second device 200. For example, if the original data regarding the object 300 cannot be obtained, the first device 100 may capture first content itself in the part of an area of the object, which is selected by the user, and transmit the first content to the second device 200. If the original data regarding the object 300 can be obtained, the first device 100 may extract second content corresponding to the first content and transmit the second content to the second device 200.

The first device 100 may let the user easily capture and transmit an image in a part of an area of a book to the second device 200 by a simple gesture selecting the part of an area of the book.
